IMPROVEMNT IN MVETALROLLING MACHINES.

Specification forming part of Letters Patent No. 151,079, dated May 19,1874 application filed April 13, 1874.

To all whom it may concern:

Be it known that I, MATTHEW H. BROOKS- BANIQof the city of Newark, Stateof New Jersey, have invented an Improved Rolling- Machine, being animprovement in that class of rolling-machines known as disk-rolls,constructed of hard metal, of which the followin g is a specication:

The object of my invention is to simplify the construction of that classof rolling-machines known as plane disk-rollers, by remodeling thegeneral arrangement; avoiding the expensive hollow shaft, which forms aconspicuous feature in my application `for improvements inrolling-machines iiled January 31, 1874, yet retaining all the efliciency and compactn ess pertaining to that design without sacrificingfacility of manipulation or excellence of working qualities, it beingintended to accomplish the same description of work as the improvedrollers above mentioned, viz., the rolling and finishing of rough roundbars of iron, steel, brass, or other metals, by reducing them to thecondition of perfect cylinders with polished surfaces, adapted forshafting, spindles, and many other useful purposes, without requiring tobe turned in a lathe, according to the usual practice.

D and D, Figures 1, 2, 3, 4, 5, are the planefaced disk-rolls, made ofhard metal, and of equal diameters, attached to parallel horizontalshafts S and S. By referring to Fig. 5 it will be seen that thedisk-roll D is somewhat higher than the other roll, D--that is, thecenter of D should be about one and one-fourth the radius of the shaftabovethe center of D, deviating from this more or less, according to themean radiuses of the bars to berolled. The two disk-rolls are connectedtogether by the spur-wheels A B and the intermediate wheel C, and whenmotion is communicated to the shaft S it is transmitted through theintervention of the 'spur-wheels B C A to the shaft S, which willrevolve in the same direction as S', carrying the disk-rollers withthem. F F F is the framing for mounting and supporting the rollers andshafts. H is a strong block, supporting the adjusting-screw k forregulating the distance of the roller D from the roller D. m is anotheradjusting=screw, to hold the shaft S and its roller D against theadjustingscrew k. E is a guide-piece, supported by the block-piece L.This guide-piece extends between the faces of the rolls, close up to theshaft S, and its upper side ranges about the same level as the upperAside of the shaft S. l? l?. is a preventer-piece, to prevent the metalbar from rising while being operated upon.

vThe inode of operating the rolls is as follows: The disk-roll D beingproperly adjusted to suit the diameters of the metal bars to be rolled,and suitable power being applied to the end of the shaft S to drive thedisk-rolls at a suitable velocity, as found by practice, a rough roundbar of metal is made hot, and the leading end inserted upon theguide-piece E, under the preventer-piece P, and pressed forward betweenthe disk-rollers D' and D. As soon as the rollersgripe the end of thebar it will commence to revolve and advance in the direction of thearrows marked on the bar N, Fig. 5. The disk-roller D being lower than Dis the cause of this advancing motion, when the rollers are revolving inthe direction of the arrows. The shaft S, which carries the disk-roll D,if desired, can be made so as to project through the roller toward theblock H, (see Fig. 1,) and the block H can easily be so modified as togive powerful support to said projecting shaft and its roll.

These disk-rollers D and D are differently arranged to thosedescribed inmy application of January 31, 1874, the latter being designed to revolvein opposite directions. 'lfhe conical-faced.disk-rollers of Reese, No.65,832, patented June 18, 1867, also revolve in opposite directions, andthe screw-threading faced rollers of Prosser, No. 103,776, patented May31, 187 0, also revolve in opposite directions; whereas, by reference todrawing, Fig. 5, it will be seen that by the relative positions of therolls to each other, and the mode of con nection by the spur-wheels,while the rollers both revolve in the same direction, those portions ofeach roller only which are situated respectively opposite a portion ofthe other roller move relatively in opposite directions. Therefore, mynew invention, its above described, is Clearly dierent to all others.

I claim- The combination of two plne-faced diskroilers, made of hztrdmetal, of equal diameters, and both revolving in the saine direction,and situated relative-1y to each other as shown,

with the shafts, spur-Wheels, supporting-frame,

the guide E, and the preventer P, and the two adjusting-screws on k, allarranged substantialiy as shown and described, and for the purposesabove mentioned.
